Integrin alpha V beta 3 Protein, Human (HEK293, His-Avi)

Integrin alpha V beta 5 Proteinas, specifically the alpha-V (ITGAV) subunit, is a versatile receptor for ligands like vitronectin, fibronectin, and others, recognizing the R-G-D sequence. ITGAV:ITGB3 binds fractalkine, acting as a coreceptor in CX3CR1-dependent signaling. It forms crucial interactions with NRG1, FGF1, FGF2, IGF1, IGF2, IL1B, PLA2G2A, FBN1, CD40LG, contributing to diverse pathways. Notably, ITGAV:ITGB3 or ITGAV:ITGB6 is a receptor for TGF-beta-1, mediating its release from LAP and playing a crucial role in TGF-beta-1 activation. Additionally, ITGAV:ITGB5 functions as an Adenovirus type C receptor during microbial infection. Integrin alpha V beta 5's integrative nature underscores its pivotal role in diverse cellular responses and signaling cascades. Integrin alpha V beta 3 Protein, Human (HEK293, His-Avi) is a recombinant protein dimer complex containing human-derived Integrin alpha V beta 3 protein, expressed by HEK293, with C-His, C-Avi labeled tag. Integrin alpha V beta 3 Protein, Human (HEK293, His-Avi), has molecular weight of 85-140 kDa.

The Integrin alpha V beta 5 protein, specifically the alpha-V (ITGAV) integrin subunit, serves as a versatile receptor for a range of ligands, including vitronectin, cytotactin, fibronectin, fibrinogen, laminin, matrix metalloproteinase-2, osteopontin, osteomodulin, prothrombin, thrombospondin, and vWF. Recognizing the sequence R-G-D in various ligands, ITGAV:ITGB3 binds to fractalkine, acting as a coreceptor in CX3CR1-dependent fractalkine signaling. Additionally, it forms essential binding interactions with NRG1, FGF1, FGF2, IGF1, IGF2, IL1B, PLA2G2A, fibrillin-1 (FBN1), and CD40LG, contributing to diverse signaling pathways. Notably, the ITGAV:ITGB3 or ITGAV:ITGB6 complex acts as a receptor for transforming growth factor beta-1 (TGF-beta-1), mediating its release from regulatory Latency-associated peptide (LAP) and playing a crucial role in TGF-beta-1 activation. Furthermore, ITGAV:ITGB5 functions as a receptor for Adenovirus type C during microbial infection. The integrative and multifunctional nature of Integrin alpha V beta 5 underscores its pivotal role in mediating diverse cellular responses and signaling cascades.
